Doesn't the fuel rail need to be purged after disconnecting it?

Factory service manual says:

Prime fuel system:
a. cycle ignition on for 5 seconds and then off for 10 seconds.
b. repeat step a twice.
c. crank engine until it starts (maximum cranking time 20 seconds)
d. if engine does not start, repeat steps a-c.

Did that. Still doesn't start.

I think that there may be a Schrader valve (like tire filling valves)
for the purpose. If you have air trapped in the fail, the injectors
aren't going to work.

Yes, it has a Shrader valve. There's pressure in the rail, and when I open the valve, fuel
comes out, not air.

O.K. Then it is purged. Is it possible that the replacement
fuel injector is bad?

DoN, why would all 4 plugs get fouled if only one injector was bad?

A badly flooded cyl can flood the rest of the engine too. Has the OP
checked his oil level on the dipstick? If the injector(s) is (are)
stuck open he will be "making oil".

My suspicion is he grounded his injectors by pinching a wire. I've
seen it happen more than once. (never done it myself, but have had to
fix a few))

Greetings Clare,
The OP said that when starting fluid was used it backfired out the
throttle body. In my experience as a shadetree mechanic when I
experienced backfire it was either an intake valve or valves that
didn't seal, for whatever reason, or the timing was off so that the
spark occurred when the intake valve was open. What other conditions
can cause backfiring on a fuel injected engine? It's nice to be able
to ask someone who really knows about cars.
Cheers,
Eric

I've had badly flooded engines backfire on ether.
That engine needs to be "dried out" which may require changing the
oil, and it needs clean dry plugs. It also needs to be checked for
injector pulses - a set of "noid" lights would make the job easier.
If the injectors are not firing it COULD be a bad sensor - but if they
are on steady he has a bad engine control computer or grounded
harness. Disconnect the computer, if they still stay on the harness is
at fault. If not, the computer.
